[cosmetics] add the files to string.po to indicate where strings are used
[rbp/omxplayer] make sure we can also abort the open of a ffmpeg input stream
[rbp/omxplayer] reevaluate HasVideo/Audio after a stream change
[rbp] Fix elapsed time not updating near end of file

Currently, once demuxer has reached EOF, we send the EOF messages to audio/video players
and set their inited/started flags to false. But if started is false we ignore any
PLAYER_DISPLAYTIME coming back from players, which stops the elapsed time from updating.
This can affect the final ~8 seconds of the file.

The fix delays changing these flags until audio/video players have signalled EOS.
[rbp] Don't block waiting for EOS in audio/video players

Currently we block in OMXPlayerAudio/OMXPlayerVideo from the point we see EOF from demuxer,
until the last frame/audio sample has been played out. This can be a few seconds.
It means no more messages (such as abort) can be received during this period.
This results in a bug where if you press stop after the demuxer EOF has occurred it takes
a long time to stop. You would expect this to be the few seconds of queued data,
but it actually turns out to be 30 seconds, as the clocks get stopped by the stop message,
but the players never find out and we hit a timeout.
It also stops seek/pause working during the playout period.
It also stops (graphical) subtitles from being rendered during this time.
The fix involves not blocking for the EOS, but allowing the polling from OMXPlayer to catch it.
[WIN32] fixed BuildSetup.bat: copy the pdb file to the build setup directory.

Since Jenkins is dependent of the "pdb" file, it is copied to the setup directory with the new name "XBMCSetup-%GIT_REV%-%target%.pdb"
Removed "dead" (commented out) line (// pic->age  = 256*256*256*64; // decrepated)
fixed, restore search_paths_first in platform_ldflags only to avoid gcc warning spew of 'linker input file unused because linking not done'
fixed compiler warning about unused var
